Twitter is now a very unfriendly place for people with left wing views. But I actually think it’s more friendly to moderates than Bluesky. And I’m not just talking about the composition of the population. If you post centrist stuff you have a higher chance of getting trolled here than there.

A lot of people on the far right present themselves as centrists because they think they've ascended politics entirely and entered a higher realm of absolute objective truths.

Uh-huh. Post a moderate opinion about how Hitler was bad and see how friendly it is.

"Moderate" is also self-ascription.

Plenty of center-left liberals here, and a few but some sane center-right, who openly don't much care for actual leftists. The only genuinely unwelcome I've seen are MAGA trolls, which... good. But "centrist" can mean lots of things, some of which get slagged because they're just plain dumb.
